I have created a virtual paper keyboard which can be used as a normal keyboard to type on screen. Now, the part that i am stuck is how do i detect the tip of my finger touch with the paper? I looked online but wasn't able to find any information. Can anyone suggest me some ideas or any article that can help me to resolve this issue?

What platform are you talking about? Figure this out and address to the appropriate touch API. It won't be really related to OpenCV.

if your working on Windows you should read Quickstart: Touch input and chase all the links.

For Apple you should dive into gesture recognizers. Easiest done via storyboard objects and event handlers. You'll get ready before understanding it. ;-)
